The protective film is in two parts (in contrast to many other, consisting of 3 parts), ie in this case may have to be taken a little more cleanliness during application. The film can be applied very well and does not hinder the "Touch" function. If, when applying some dust or lint have come to the film, they can be well re applying moist. For this, the whole film is cleaned by running water, shaken off the water and then applied onto the display. So you can avoid any dust inclusions. Here, of course, some caution should be exercised so that no water enters the unit. It is best with an absorbent cloth immediately exiting droplets on. Works for me anyway excellent. The film makes a robust impression. It is hardly to be seen at first sight on the display. I would recommend it.
